We are looking at the S27A850 unit that comes in boast WQHD resolution. For those of you not up to date on that particular specification, that means the screen comes in at 2560x1440. It follows a 16:9 aspect ratio instead of the 16:10 aspect ratio of my trusty 30 305T display (2560x1600). This screen has a few other features other than just a nice high resolution and I can honestly say that the screen can go bright enough to light up your entire office. . ."
